[jira] [Created] (MAPREDUCE-4467) IndexCache failures due to missing synchronization

Andrey Klochkov created MAPREDUCE-4467:
------------------------------------------

             Summary: IndexCache failures due to missing synchronization
                 Key: MAPREDUCE-4467
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4467
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 0.23.2
            Reporter: Andrey Klochkov


TestMRJobs.testSleepJob fails randomly due to synchronization error in IndexCache:

{code}

A related issue is MAPREDUCE-4384. The change introduced there removed "synchronized" keyword and hence "info.wait()" call fails. Tbis needs to be wrapped into a "synchronized" block.
